Overview

The HKS 50003-M45G-1 is a spark plug designed for high-performance applications. It features a 0.6mm iridium alloy center electrode for improved ignition performance and durability. The plug also incorporates a short type outer electrode for anti-vibration and a thermal edge on the ceramic insulator to help prevent carbon buildup.

This spark plug is recommended for reliable ignition, durability, and anti-carbon buildup under high load conditions. The iridium alloy's high melting point allows it to tolerate high compression and minor knocking without deterioration. A nickel coating on the housing further prevents premature deterioration.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
